Constructor Summary
protected PrimitiveSparseArray.Iterator(AbstractSparseArray.Node head, int fromdir, boolean fForward)
          Instantate a new PrimitiveIteartor at the specified location and direction.
 
Method Summary
 long getPrimitiveValue()
          Returns the current value, which is the same value returned by the most recent call to the nextPrimitive method, or the most recent value passed to setPrimitiveValue if setPrimitiveValue were called after the nextPrimitive method.
 long nextPrimitive()
          Returns the next element (as a long) in the iteration.
 long setPrimtiveValue(long lValue)
          Stores a new value at the current value index, returning the value that was replaced.

Constructor Detail

PrimitiveSparseArray.Iterator

protected PrimitiveSparseArray.Iterator(AbstractSparseArray.Node head,
                                        int fromdir,
                                        boolean fForward)
Instantate a new PrimitiveIteartor at the specified location and direction.

Parameters:
head - the node at which to start the crawl
fromdir - the direction in which to start the crawl
Method Detail

nextPrimitive

public long nextPrimitive()
Returns the next element (as a long) in the iteration.

Returns:
the next element (as a long) in the iteration
Throws:
java.util.NoSuchElementException - iteration has no more elements

getPrimitiveValue

public long getPrimitiveValue()
Returns the current value, which is the same value returned by the most recent call to the nextPrimitive method, or the most recent value passed to setPrimitiveValue if setPrimitiveValue were called after the nextPrimitive method.

Returns:
the current value
Throws:
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

setPrimtiveValue

public long setPrimtiveValue(long lValue)
Stores a new value at the current value index, returning the value that was replaced. The index of the current value is obtainable by calling the getIndex method.

Returns:
the replaced value
Throws:
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
